Matsyasana (The fish pose)
Lie down flat on your back. Bring the feet together. Place your hands with palms downwards beneath the thighs close to the buttocks. Then lift the chest up by pushing the elbows into the ground. When the chest is as high as possible and in a comfortable position, drops the head back so as to touch the floor.
Remember that the weight of the body should rest only on the elbows and not on the head. With the chest arched in that manner breathe deeply. Remain in the position for one minute or so. To come out of the position, first lift the head and straighten the back and then slowly lower the upper body to the ground. Relax.
Benefits: Stiffness in the muscles around cervical, thoracic and lumbar regions is reduced. Strengthens the lungs. A good exercise for asthma patients.
